Hi All,
Would probably by useful if there was a brief fact sheet on this as it appears I am not the only person struggling to get correct M8 bolt.
It is suggested on here that a 1.5 or 15 mm thread is required.
Standard thread size for M8 I believe is 0.7 mm.
If it is 1.5 supplier links would also be appreciated.
Thanks,
Mike

If its the threaded inserts in the roof, be sure to use a corrosion proof / stainless steel bolt. If they bind at all you can have a fun time trying to get them out as the inserts may lose their grip on the roof structure (from old half remembered memory!)

Yes to be fair the set of M8s I had already got from ebay did the job:
